.HENRY P. GROOKETT, OF BATTLE GREEK, MICHIGAN, ASSIGNOR TO ALANS ON H. KEENEY,

OF AUGUSTA, MICHIGAN.

MACHINE FOR DRYING, SCOURING, AND CLEANING GRAIN.

To all whom it may concern:

Be it known that I, HENRY P. CRooxETT, a citizen of the United States of America, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Machines for Drying, Scouring, and Cleaning Grains; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

My invention relates to improvements in machines for drying, scouring and cleaning grains, and its object is to provide the same with various new and useful features hereinafter more fully described. and particularly pointed out in the claims, reference being had to the accompanying drawings, in which:

Figure 1. is an elevation partially in vertical section of a device embodying my invention; Fig. 2. a plan view of the same with parts removed to show the construction; Fig. 3. an enlarged detail illustrating the construction of the frame and the case and shown in plan view; Fig. 4. a vertical section of the same; Fig. 5. a plan view of one of the spiders; Fig. 6. an elevation of the same with parts broken away; Fig. 7. a detail of the center of one of the outwardly inclined floors; Fig. 8. the same of the inwardly inclined floor; Figs. 9 and 10 enlarged details of one of the paddles and Fig. 11 a detail illustrating the manner of securing the various sills to the collars surrounding the shaft.

Like numbers refer to like parts in all of the figures.

The device is provided with a cylindrical case made of superposed sections 1, 2, 3, and 4, the number of these sections being more orless according to the size of the machine required or the space in which it is erected and each section provided with one or more doors 5, as occasion requires. These superposed sections are connected by iron bands 45, the vertical members of which bands overlap the seams between the sections and to which bands the sections are secured by removable bolts, as shown in Fig. 4,

Each floor consists of a series of segmental plates supported upon iron sills 10, which Specification of Letters Patent.

Application filed October 21, 1907.

Patented June 16, 1908.

Serial No. 398,447.

sills are secured at their outer ends to the bands 45 by means of the same bolts that secure the lower edge of the case sections. These irons 10 are fitted to the bands 45 by removing a portion of the horizontaltop member and bending the extending vertical member of the sill at right angles and perforating it to receive the said bolt as illustrated in Figs. 3 and 4. Various collars 12, 13, 14 and 15 surround a vertically disposed rotative shaft 11 in the axis of the case, in which collars this shaft is rotative, the upper collar 12 serving as a journal bearing for the shaft. The inner ends of the sills 10 are secured to the respective collars by removing a portion of the vertical member of the sill and bending the horizontal member downward and. securing the same to the collar by screws 43 inserted therein as illustrated in Fig. 11. The segmental plates supported upon these sills constitute various floors 6, 7, 8 and 9, four being shown, which floors are all except the lower one perforated with small perforations to permit the hot air to pass upward therethrough and also to allow the fine particles of dust to pass downward. These perforated floors 6, 7, and 8 slant alternately outward toward the periphery, and inward toward the axis of the structure, the lower perforated floor 8 having an outward slant and the bottom floor 9 which is not perforated has a corresponding outward slant. The outwardly inclined perforated floors except the lower one also have large openings 34 at the periphery to discharge the grain downward upon the periphery of the next floor below and the inwardly inclined floor 7 is open at the center as illustrated at 35 in Fig. 8. to discharge the grain downward upon the next floor below.

The material to be dried is supplied through a spout 30 in a conical hood 28 suspended above the machine, and provided with a pipe 29 at the apex to collect and carry away the steam and hotair. The lower perforated floor has no openings at the periphery and in the case is a discharge spout 31 to receive the dried grain from this floor and convey the same away from the machine. The dust passing through the small openings in the various floors accumulates upon the imperforate floor and 9 is discharged into a spout 33 arranged at the periphery of the same. gear 27 fixed thereon and engaged by a pinion 26 mounted on a driving shaft rotated by any convenient means.

The grain is stirred and moved on the various floors by means of a number of small paddles 22 arranged. to traverse close to the respective floors at their lower ends and at their upper ends adjustably attached by means of bolts to the horizontal member of iron sweeps 20 arranged parallel with and above the floors and extending radially from the shaft, being attached thereto and rotated thereby by means of spiders 16, 17 and 18 vertically adjustable on the shaft and having arms to which the angle bars are pivotally attached at their inner ends by cap screws 39 inserted in openings in the arms and adjustably supported by bolts 38 inserted in vertically elongated openings 41 in the spider arms whereby the sweeps are adjusted parallel with the floors and by adjusting the collars vertically on the shaft, the paddles 22 may be brought in close relation to the various floors. The paddles are also adjusted about the vertical axis of the bolts which secure them to the arms at an inclination to radial lines so that they move the grain outward on the outwardly inclined floors and inward on the inwardly inclined floors. To further insure the movement of all of the grain on the floors chains 23 may be attached to these paddles which drag upon the respective floors. Above the lower and imperforate floor 9 is an arm 21 carried by a bracket 19 secured to the shaft, and a drag chain 24 attached to this arm engages and traverses the said floor whereby the dust and small particles are gradually moved outward toward the periphery of the floor and discharged into the spout 33. A pipe 32 arranged tangential to the lower section 4 of the case admits a current of hot air from any convenient source between the imperforate floor 9 and the next floor above, which air passes upward through the various perforated floors, escaping into the hood 28.

From the foregoing description, the operation of my device is obvious and needs no further explanation.

What I claim is:

1. In a drier for drying, scouring and cleaning grains the combination of superposed and alternately inclined conical and perforated floors, a shaft in the axis of the same, sweeps attached to the shaft, paddles attached. to the sweeps and inclined to radial lines, chains attached to the paddles and engaging and traversing the floors, means for admitting and removing air, and means for admitting grain and removing the same.

2. In a drier for drying, scouring and cleaning grains superposed and alternately inclined and perforated floors each having The shaft 11 is rotated by means of a I openings at the lower part thereof to allow the grain to pass to the floor below, means for stirring and moving the grain downward on each floor, an imperforate floor beneath the lower perforated floor, means for admitting and removing air, means for removing removing grain, and means for admitting grain.

3. I11 a drier for drying, scouring and cleaning grains the combination of superposed alternately inclined perforated and conical floors, each having openings at the lowerpart for the escape of grain therefrom, an imperforate conical floor below the perforated floors, means for admitting air, a rotatached to the shaft and traversing above each floor, chains attached to said sweeps and traversing the respective floors, means for admitting grain, means for removing grain, and means for removing dust from the lower part of the imperforate floor. j

4.
